NSWGR railway crossing control, bi-directional tracks, double-track fixed road length, no fixed tracks

A railway crossing employed by NSWGR in the mid 20th century. The default fixed road is replaced by the road asset the user connects to it. The fixed road is long enough for the user to run 2 railway tracks over it at an angle between 60 and 120 degrees.
The user-laid tracks are assumed to be bi-directional, and so there are no dedicated 'down' or 'up' tracks.
Intended for use as a core element in a kit allowing the assembly of crossings tailored to their locations. The kit comprises the following KUID 368725 assets:
20384 - NSWGR railway crossing boom gate, lefthand
20385 - NSWGR railway crossing boom gate, righthand
20519 - NSWGR railway crossing road gate pair, manual
20523 - NSWGR railway crossing road gate, manual, cw
20524 - NSWGR railway crossing road gate, manual, acw
20386 - NSWGR railway crossing pedestrian gate, remotely operated, lefthand
20387 - NSWGR railway crossing pedestrian gate, remotely operated, righthand
20522 - NSWGR railway crossing pedestrian gate, user operated
20388 - NSWGR railway crossing warning light, post mount, red flash
20389 - NSWGR railway crossing control, single fixed track, sealed road
20517 - NSWGR railway crossing control, single-track fixed road length, no fixed track
20390 - NSWGR railway crossing control, uni-directional double fixed track, 12ft spacing, sealed road
20525 - NSWGR railway crossing control, bi-directional tracks, double-track fixed road length, no fixed tracks
20391 - NSWGR railway crossing pedestrian boards, single track
20392 - NSWGR railway crossing pedestrian boards, double track, 12ft spacing
60013 - Operate railway crossing (driver command)
Also important for the kit's operation is KUID:76656:70010 'Directional Trigger'.

Some compatible road assets are:
30154 - Tertiary 2L,8m rural road, unsealed, grey dust on gravel, 40mph (65km/hr)
30171 - Tertiary 2L,8m rural road, unsealed, grey dust on gravel, no traffic
30155 - Tertiary 2L,8m rural road, unsealed, brown dust on gravel, 40mph (65km/hr)
30172 - Tertiary 2L,8m rural road, unsealed, brown dust on gravel, no traffic

For correct communication between this control asset the other animated kit components(gates and lights) in use, a naming convention must be followed.
All in-game names given to the kit components have 3 or 4 elements separated by underscores.
The first name element is the location code for the crossing. This can be any alphanumeric, except in the following cases:
(a) if the crossing is to be controlled from a lever frame such as <kuid:368725:90030> 'NSWGR mechanical lever frame for a signal box, 18-28 levers, for avatar operation', then the crossing location code must be the same as the location code of the lever frame.
(b) if crossing protection signals (see below) are to be selected then the crossing location code must be the same as the location code for the local signals.
The second name element must be one of 4 keywords that identified the type of kit component: 'crossing control','road-barrier','ped-gate','light'. A boom and a road gate pair are classed as a 'road-barrier'.
There may be more than one crossing at a location, so the third name element is an index commencing at '0' for the first instance, and so on.
Kit components other than the crossing controls can have multiple instances for the one crossing. These instances are indexed by a fourth name element, commencing at '0'.
For example, the first and only railway crossing at Hawkesbury River (location code 'HR') has 2 pedestrian gates. The second gate is referenced as 'HR_ped-gate_0_1'.
The user can select from 2 modes of train detection in each direction (DOWN and UP) for setting the state of the crossing: a directional trigger or a driver schedule command.
Directional triggers (KUID:76656:70010) are used to detect the approach of a train from the Down or Up directions. 1 or 2 triggers are required for each direction, depending on the track layout.
For example, the crossing may be located near the Down end of a passing loop for a single main line. The crossing detection point for an Up trai
